Active distributed antenna system with frequency translation and switch matrix

Abstract

A three-dimensional, 360 degree, omnidirectional multiple-input multiple-output wireless systems is described herein. The multiple-input multiple-output wireless system is comprised of a plurality of radio inputs, a plurality of radio-frequency converters, an RF signal distribution network, a plurality of transceivers, and a plurality of antennas. The multiple-input multiple-output wireless system may further have a plurality of planar stacks.

AI Technical Summary

Benefits of technology

The present invention is a wireless system that integrates the features of a complex structure that can address 360 degrees of azimuth and 60 degrees of elevation, with the ability to simultaneously up-convert and down-convert multiple external radios. The structure's beam can be quickly directed to different sub-regions using a finite set of solid angles, and each sub-region can have its own separate beam that can be distinguished based on carrier frequency, polarization, and power level. This system can be used in electronic warfare and is suitable for dual-use technologies.

Problems solved by technology

Both of these methods must overcome the inertia of either the mechanism, or of the phase control actuating element, an inertia which in turn limits the agility with which the beam may be redirected.
